Hundreds of House districts are being redrawn. Here’s who’s winning and losing.

Every 10 years, each state redraws its political lines. These processes take months to unfold in state capitals all around the country — and their results mold the balance of power in Congress for a decade.

Our analysis uses local voting tallies and Census data to decode what these new lines mean. We'll update this report as states approve new maps — and for up-to-the-minute redistricting news, be sure to subscribe to Weekly Score.
